Reaction Steps

To a suspension of ethyl 3-[(2-bromoethyl)oxy]benzoate D46 (476 mg) and potassium carbonate (481 mg, 3.48 mmol) in Acetonitrile (20 mL) stirred at 20° C. was added 3,3-difluoropyrrolidine (250 mg, 1.741 mmol). The reaction mixture was stirred at 70° C. for 36 h. After cooled to room temperature the mixture was filtrated and the filtrate was concentrated. The crude product was added to a silica gel column and was eluted with Hexane/EtOAc/TEA in ratio 50/50/0.5. Fractions isolated and solvent evaporated to afford the title product D49 in 400 mg as a yellow oil. LCMS Retention time=1.20 mins, [M+H]+300 (5 min run)
